Armormmn CONSTRUCTION A pplication filed;March 25, 1931. Serial No. 525,177.-

This invention relates to improvements in aeroplane construction and the invention contemplates certain improvements overthe idisclosure of my pending application, Serial No. 467,669,-filed July 14th, 1930.

One of the objects of the invention is to provide new and improved means whereby 'theieiliciency ofthe atmospheric pressure pro- 1 duced by the 'forwardmovement of'the plane may be more effectively utilized in the lifting of the plane and the'holding ofit aloft. Another object of the inventionis to provide new and :improved means whereby a- "greater degreeof sub-atmospheric pressure .may beproducedfby the forward .movement Lof the plane through the atmosphere thereby giving a greater liftingforce per g1ven-un1t of wing area. a

Another object of the invention is to pro- 0 wide anew and improved wing for aeroplanes whereby the sub-atmospheric pressure utilized in maintainingjthe plane aloft is effec- .tively. assistedlbyutilization of the air currents passing-beneath the. wing of the plane.

A further object of the invention is to providea'new and improved arrangementof the propeller relative to the wing of the plane whereby theaircurrentsproduced by therev- .olutiou'of thelpropeller will be utilized ;to lsu ch an extentthat the planewill be caused .to rise fromthe-ground withoutthe necessity of "liaving:to make a run. 7

'Other' objects ofthe invention will be in partobvious and in part pointed Outhereinafter.

[The invention accordingly consists in the 'I provide alplurality of. inclined vanes}, 0

' permit-the air currents passing rearwardly by the plane to form a sub-atmospheric pres:

taken on "the line 3'-3.of Figure 2, looking in.v the direction of the arrows, and

' Figure 4 is a fragmentary plan View of the. upper surface of the .wing. V Referring now to the. drawing wherein similar reference characters refer to similar parts throughout thes'everal views thereof, the reference numeral ldenotes the fuselage of the plane which may be of conventional form. a '60 Numeral 2 indicates themotor, and numerals 3 and 4 denote the usual vertical and horizontal rudders provided in aeroplane construction. (q

The reference numerals 5 and 6' denote the wings of'the plane which are secured in any approvedmanne'r to the fuselage 1. I

Referring now, to the wing construction which is illustrated best in Figures 3 and 4:,

which are spaced apart .and suitably connected to the upper andlower. walls of the wings; These vanes areinclined rearwardly from the bottom wall tothe top wall of; the plane providinga plurality of spaces8 between'the vanes. a

Extending from the'top or upper edge 9 of each vane is a partitionlO which'extends downwardly and forwardly and joins with a the lower end or edge 11,0f the neighboring vane as isclearly shown in Figure 3 of the drawing. These partitions extend lengthwise to each wing and form a'barrier preventing air from' passingthrough the wing from thelower surface to the upper. surface, thereof. They are preferably formed of an elastic material suchasrubber, although in some instances they may be made of a relatively stiff and non-elastic material.

The forward edge. of the wings, it will be 7 noted, is relatively, sharp, said edge being formed by a. wall 12, which extends downwardly and forwardly'from the upper edge 13 ,of the wing joining a forward extension '14 of the wing at arelatively sharp angle. This forward edge of the wing is preferably formed with longitudinally extending aper tures 15 and 16, the purpose of which is to wardly through the pip.eJ-by"means of the;

sub-atmospheric pressure produced in the compartment 17 or in the a shaped spaces 19 of the wing of the plane. This trap 20 will at all times contain water.

If desired,-side wings 21 and 22 may be provided upon thes'ide walls of the fuselage as shown in my aforementioned co-pending application and these wings may also be constructed in a manner similar to the construction of the wing I have above described.

Having thus described the construction of this embodiment of my invention, it will accordingly be seen that 'I have provided means whereby lifting effect of the air through which the wings of the aeroplane are forced by the motor maybe more effectively utilized, having provided on the top of the wing a plurality of independent chambers which at all times will contain a subatmospheric pressure when the plane is in motion.

I have also provided means whereby the effect of the air currents through. whichthe plane is being forcedby the motor and passing underneath the wing of the plane entering the inverted V shaped pockets 23 formed by the partitions 10 and their wings will be more efi'ectively utilized in lifting the plane. In other words, I have provided fora higher degree of vacuum on the top surface of the plane than it has heretofore been possible to obtain, and I also-provide pockets on the under-surface of the plane whereby the air under pressure is maintained exerting an upward and forward stress onthe wings of the plane. 7

It will also be noted that the relation of I the propeller and the wing is such thatthe air currents produced by the propeller will have the effect of quickly lifting the plane from the ground. I

The pipe or condmt WlllCl'l extends transversely of the wing and to therear end of the fuselage is utilized to conduct water from the compartment 14: of the wing and from the V shaped pockets formed upon the upper surface of the wing. The trap being filled with water effectively prevents air from passing forwardly through this pipe, which air mightqnterfere with the degree ofsubatmospheric pressure produced in the V shaped pockets formed :in the upper wall and in the front compartment thereof.

As-many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted asillustrative and not in a limiting sense. r i

It is also to be understood that the language used in the following claims is intended to cover all 'ofthe generic and specific features of the invention herein described, and all statements of the scope of the invention,which, as a matter of language might be said to fall therebetween.

-: Having thusdescribed myinventiomwhat I claim as new and desire to secure byLetters Patent is:

1. In aeroplane construction, a wing having a plurality of air tight pockets upon its" upper and lower surfaces, and an elastic parition wall separating said pockets.

2. In aeroplane construction, a wing having in its upper surface aplurality 'of air tight pockets andin its forward edge a coming from the upper edge of each partition to the lower edge of the partition located forwardly thereof, 7

1. In aeroplane construction, a wing having a plurality of vertically and rearwardly disposed vanes, said vanes being rigid and V spaced apart, and'an elastlc partltlon wall joining the upper edge of each vaneto the loweredge of the adjacent vane. I U

5. In aeroplane construction, a wingjhaving aplurality of vertically and rearwardly f disposed vanes, said vanes being rigid and spaced apart, means running transverse/0f said vanes to which said vanes are anchored,

and an: elasticpartition walloining the upperedge of each vane to thelower edge of the adjacent vane.

6. In aeroplane construction, a wing having a plurality of vertically and rearwardly disposed vanes, said vanes being rigid and spaced apart and inclined rearwardly from the lower surfaceto the upper surface of the wing, and, an elastic partition wall joining the upper edge of each vane to the lower edge .of th adjacent vane forwardly .dis-

posed thereto. 7

7. In aeroplane construction, a wing.hav-- inc; a plurality of vertically and rearwardly disposed vanes, said vanes being spaced apart and inclined rearwardly from the lower. surface to the upper surface of the wing, and

8. In aeroplane constructlon, a wing having a plurality of pockets upon its upper surface, said pockets being formed by a plural ity of vertically and rearwardly disposed rigid vanes spaced apart and having an elastic partition wallconnecting the upper edge of each vane to the lower edge of the vane forwardly adjacent thereto.
